Rick Zitzmann
ENGINEER
After graduating with a degree in Mechanical Engineering, Rick cut his bicycle industry teeth in the mid 90’s in the engineering dept at SAPA (back then Anodizing Inc). After gleaning five years worth of production manufacturing experience, Rick decided to strike out on his own, getting in on the design end. Since then, Rick has helped a multitude of companies bring their dreams to reality, providing design engineering, and coordination and support in bringing these designs to manufacturers. Currently, Rick is very excited to work with Zen Bicycle Fabrication, as he believes there is an advantage in keeping production close to home, especially so for small batches of product and can think of no better place to do that then in Portland, Oregon.
Hometown – Portland, Oregon
Rick likes to vacation anywhere warm and tropical
Beverage of choice – Hornitos Plata
Jonathon Sieber
WELDER | FABRICATOR
Jon started riding road bikes in the late 80's in High school, then in the early 90's got in to mountain biking. Jon was taking an art class in collage and fell in love with welding and enrolled in welding school. After welding school Jon got a job at Anodizing Inc tacking frames, combining two things he loved. Jon moved over to Kinesis USA and grew as a frame builder. Jon worked with some guys from Kinesis and started Tonic Fabrications and for a few years that was a fun project. Jon left Tonic and started Cascadia Bicycles as a one man show. Jon went to work at Specialized as their prototype frame builder down in California for a few years but could never really pull up roots from Portland. After returning to Portland, Jon found Zen and all is right in the world again.
Jon’s favorite place to ride is some place new with sweet single track.
He loves pizza so much that he built a wood fired pizza oven in his back yard.
Favorite alcohol - Beer from a can.
What do you want to be when you grow up - No, thank you he doesn’t want to grow up.
Jon’s pets are Lucy, the prettiest dog in town and NovaPoopsAlot, his cat that has just found it voice after 13 years and is making up for lost time; MEOW.
Favorite TV show- Twin Peaks.

Favorite quote – “It’s not the critic
who counts, not the one who points out how the strong man stumble or how
the doer of deeds might have done them better. The credit belongs to
the man who is actually in the arena, whose face is marred with sweat
and dust and blood, who strives valiantly, who errs and comes short
again and again, who knows great enthusiasms, the great devotions, and
spends himself in a worthy cause, and who if fails at least fails while
daring greatly, so that his place shall never be with those cold timid
souls who know neither victory nor defeat.” – Theodore Roosevelt
